Gigabyte GTX1080 Windforce Graphics Card Ethereum Hashrate

75% power limit on that MSI Gaming X 1080 at 180 watts is IDENTICAL to a lot of other GTX 1080 cards at 100% TDP - specifically including all of my Gigabytes 1080 cards (2 models) and my Zotac Mini 1080 models. source

I only tried a 1080 once for ETH (GB Xtreme) and got only 25.5 mh/s.
You would be much better of mining zcash with a 1080 --> They are really nice for it with 520-570 sol/s per Card. source

Using linux and tuning OC and power settings nicely, I managed to get 23Mh/s on ethereum using 100W with a gigabyte gtx 1080 oc 8g (windforce).
Still a far cry from the 1070's nice hash rates, but quite happy with power consumption. source
